Characteristics 30BQ040 Units

The 30BQ040 surface-mount Schottky rectifier has been de-

signed for applications requiring low forward drop and small

foot prints on PC boards. Typical applications are in disk drives,

switching power supplies, converters, free-wheeling diodes,

battery charging, and reverse battery protection.

Small foot print, surface mountable

Very low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
